Summary
The protocol underlying almost all web traffic, and TLS — the encryption layer securing it — understanding the TLS handshake and certificate validation is essential for spotting man-in-the-middle attack risks.
How to Learn This
- 1Inspect a website's TLS certificate details in your browser.
- 2Learn the basic steps of a TLS handshake and where it can be attacked (e.g. downgrade attacks).
- 3Understand why HTTPS alone doesn't guarantee a site is trustworthy, only that the connection is encrypted.
